Abstract Pollen data from China for 6000 and 18,000 14 C yr bp were compiled used to reconstruct palaeovegetation patterns, using complete taxon lists where possible a biomization procedure that entailed the assignment of 645 pollen taxa plant functional types. A set 658 modern samples spanning all biomes regions provided comprehensive test this showed convincing agreement between reconstructed present natural vegetation types, both geographically in terms elevation gradients mountain...
Sandy red clay, abundant in clay minerals, exhibits a marked sensitivity to variations water content. Several of its properties are highly prone deterioration due wet–dry cycling, potentially leading slope instability. To investigate the multi-scale patterns and underlying chain mechanism sandy subjected cycles, this study conducted systematic tests on remolded specimens through 0 5 with number cycles (N) as variable. The study’s results indicated following, under cycling: (1) Regarding...
Slope stability analysis requires particular attention to groundwater effects, where seepage–stress coupling fundamentally alters mechanical responses. This investigation develops a field-calibrated numerical model using monitoring data from water diversion project in Yunnan, finite element based on theory. Comparative assessments through strength reduction methodology evaluate three scenarios: non-seepage conditions, interaction, and cutoff wall implementation. Results demonstrate the...
Serious slope erosion occurs in the distribution areas of fully weathered granites, and rainfall intensity gradient are important factors affecting erosion. In this study, we investigate characteristics Longling completely weather granites with a focus on effects gradient. Based an indoor 60-min simulated test, selected four gradients (10°, 20°, 30°, 40°) three intensities (50, 80, 110 mm/h) for evaluation. A total 12 groups tests were conducted to analyze surface hydrodynamic granite slope....
Heavy or intermittent rainfall can cause slopes to become unstable and erode, resulting in significant damage, loss of life, destruction property. Targeted management solutions are based on an analysis slopes’ flow generation sediment production patterns during periods rainfall. This study used a fully granite backfill slope as its research subject examined the features erosion We processes soil rain through indoor artificially simulated experiments. Three events with 220 mm/h intensity were...
The slope erosion in the distribution area of completely weathered granite is often relatively severe, causing serious ecological damage and property loss. Ecological restoration most effective means soil control. Taking backfill as research object, two types protection plants, Vetiver grass Pennisetum hydridum, were selected. We analyzed these herbaceous plants’ reinforcement effects through artificial planting experiments, indoor simulated rainfall direct shear tests. test results showed...
The Sichuan‐Yunnan‐Guizhou Pb‐Zn triangle area is located in the western margin of Yangtze Block and comprises more than 400 ore deposits or prospects. This triangular contains 200 million tons ores at average grades 5 wt.% Pb 10 Zn. bodies are mainly distributed as stratoid vein types within Neoproterozoic to Permian carbonate rocks, which typical epigenetic mineralizations. Previous studies have focused on individual deposits. In this study, compositions C‐H‐O‐S‐Pb‐Sr isotopes...
The Sichuan-Yunnan-Guizhou (SYG) zinc-lead triangle, located in southwestern China, is an important producer of zinc, lead, silver, and critical raw metals such as germanium. In this region, most Zn-Pb deposits hosted the later Ediacaran to Permian carbonate rocks are believed be Mississippi Valley-type (MVT) deposits, while origin found Mesoproterozoic basement remains controversial. To address gap, our study conducted situ LA-ICP-MS/MS muscovite Rb-Sr dating apatite major, trace Sr isotope...
The porosity and permeability of the rock surrounding lead–zinc deposits are key factors for controlling migration precipitation ore-forming hydrothermal fluid. In this paper, Huize super-large deposit was taken as case study, variations in wall rocks their relationship with orebody were analyzed by using CT scanning technology. experimental results showed that average pore radius dolomite a decreasing distance to ranged from 1.60 1.65 μm, increasing 1.77~2.05 μm. increased 2.76%–2.81%...
江南钨矿带是近年来中国新发现W矿床最多的成矿区带之一,是近年研究热点地区。该钨矿带的东部主要发育与弱分异I型花岗质岩石密切相关的W-Mo矿床,其成岩成矿机制和条件还不清楚,成岩条件研究是该类型矿床成岩成矿模型研究的基础。因此本文以竹溪岭W-Mo多金属矿床为例,利用角闪石-斜长石温度计、角闪石全Al压力计,角闪石氧逸度计算和黑云母氧逸度投图结果,限定花岗闪长岩的成岩条件,在此基础上,探讨成岩模式。结果显示:早期结晶的角闪石结晶温度为849~881℃,压力为241~330MPa,对应结晶深度9.11~12.4km,log <i>f</i><sub>O<sub>2</sub></sub>=-12.8~-12.2;角闪石主结晶阶段的温度为774~841℃,压力为123~209MPa,对应结晶深度为4.40~7.90km,log <i>f</i><sub>O<sub>2</sub></sub>=-13.9~-12.7;黑云母结晶时的氧逸度log...
